The DC-204R/DC-204Ra is a compact flash recording type 4-channel dynamic strain recorder and measures strain, DC voltage and thermocouples. The DC-204Ra equips an analog output of ±5V to enable, waveform output to external recorders, display devices and automobile ECU. As compared with the previous model DC-104R/DC-104Ra, the frequency response is upgraded to 10kHz and sampling speed to 200kHz at the fastest. At the same time of measurement, measured data are automatically stored on a compact flash card up to 2GB. Using the controller DC-7204 as bundled software, the maximum 8 units (32 channels) including the DC-104 series can be used together. In addition to numerical monitor and waveform display, dynamically variable amount can be displayed in analog form and in real time. The battery-operating all-in-one model is optimum for measurement on a high speed moving body. AC operation needs a power adaptor as an option.

The recorder is compatible with a compact flash card adapter of 32MB to 2GB. The formatted flash cards are available from TML.

Measured data can be stored in not only CSV format but BIN format conforming to commercial software DADiSP for data analysis of dynamic phenomena. The bundled software CONTROLLER DC-7204 can get the data stored in CSV and BIN format.

The DC-204 series has a frequency response of DC to 10kHz. The maximum sampling speed is 200kHz with one channel. Reading of the stored data from the CF card during measurement and monitoring the measuring waveform data in real time are possible. (N.B. The sampling speed is restricted.)

The DC-204 series bundled software CONTROLLER DC-7204 can monitor dynamically variable amount in analog form and in real time with bar graph and circular graph as well as numeric values and waveform.

DADiSP is available as a separate software package from DSP Development Corporation in the USA.

It is compatible with a flash memory card of 32MB to 2GB in memory capacity. The formatted CF cards are available from TML. TML does not guarantee operation of commercial CF cards.

In case of accidental power degradation during measurement, the built-in UPS circuit stops measurement and gets measured data automatically and safely stored on the CF card. Even if power supply is suddenly interrupted, the power switch is designed to turn off after recording the measured data on the CF card.

Using the supplied analog output cable (CR-3610), the DC-204Ra can output 4-channel live waveform to external recorders and display devices.

It is as small as 15.7x8.4cm like postcard and 4.2cm in height, suitable for vehicle onboard measurement. The 4-channel unit can be connected in parallel up to 8 units (total 32 channels).

* 1 channel use

The highest sampling speed is 5µ sec.* with one channel and the measured data are recorded on a specified CF memory card at the same speed. The relationship of recording time (measuring time ) with sampling speed is tabulated below. The measuring time depends on the data size.
